This invention relates to slug casting machines, wherein printing slugs or type bars are cast in a slotted mold and delivered by an ejector advancing from the rear against the edge of the slug. In these machines, the molds are adjustable in length to produce slugs of different lengths, as for printing columns or pages of difierent width, and the I ejector employed is therefore constructed so that it may be varied in Width to correspond with changes in the length of the mold slot.

For instance, as illustrated in U. S. Letters Patent to John R. Rogers, No. 967,976, there is commonly employed a composite ejector comprising a series of blades arranged edge to edge in contacting relation, and suitable devices whereby any desired number of blades can be connected with the ejector slide While the others are left free and remain at rest. These ejector blades are quite thin, being made so to serve for the ejection of very thin slugs, as well as of the thicker slugs.

In recent years, there has been a growing tendency to increase the thickness" of the 2 printing slugs and to such extent that the ejector above described is sometimes found to be incapable ofejecting'theslugs from the molds in a thoroly satisfactory manner. Thus, it frequently happens that the ejector, 39 because of its thinness, Will embed itself in the bottom edges of the slugs and fail to'eject them fully from the mold, or that, because of undue resistance ofi'ered by the slugs, the ejector bladesor other ;parts of :the machine Will be damaged in theact of ejection. These objections arise particularly with .the larger or thicker slugs, whichare of the ribbed variety, i. e., comprise a solid bodyportion, an overhanging type-carrying portion, andaseries of :ribs cast on the .bodyportion and giving support .to the overhanging portion." in the ejection of such ribbed slugs, the

ejector is arranged'toengage only vvith the solid body portion and since such portion islocated Wellto one side ofthecentralplane of theslugs, the latter havea tendency to cant or tilt in the -mold and :thereby .ofi'er greaterresi-stanceto-ejectionthan insthe case come these'and' other objections and contemplates an ejector which may not only be ad justed in Width,-'but which may be adjusted in thickness as Well, so as to be capable of ,55 cooperatingwith slugs of all dimensions, Whetherlong or short or thick or thin, In the specific embodiment, illustrated, the ejector proper. is made up of two sections, one a main section comprising a series of vertically disposed blades arranged edge to edge in contactingorelation, and the other a supplemental section comprising a series of blades disposed horizontally'in superposed parallel relation alongside the main blades. ,05 Both ejector sections are operated from a" common actuating slide, means being provided for connecting the main section alone or both sections conjointly to the slide, as required. 10 Thus, When casting thinslugs, "the main ejector section is used alone, the blades of this section, due to their thinness and vertical disposition,being capable of ejecting such thin slugs; hereas, when casting thiokerns slugs (which as before stated are usually of the ribbed variety) both the main sectionzand the supplemental section are used together, the main set of blades being arranged to engage the slugs by their solid body portions, and the supplemental set ofblades being arranged to engage the slugs by their ribbed port ons. In this Way,'as Will be readily apparent, the effective thickness of the ejector may be changed at Will to correspond :tothe thickness of the slugs being cast.

In a second embodiment illustrated, :the ejector is shownas comprising a-secondsupplemental section (orthreesections altozontally edgeto edge With the bladesofthe first suplemental set. By ,the useof such a tllli'ClSGtof'blades, three diderentthicknsses ,ofejector are available. Of course, if desired,- even a. greater number of sect ons could be employed.

:In both embodiments, provision is also made for varying the Width of the.,ejector sectionstocorrespond to the varying lengths .100

of the slugs to be cast. This is accomplished by connecting any selected number of blades of the main section to the actuating slide while leaving the remaining blades free or disconnected from the slide. The variation in width of the supplemental section or sections is accomplished in the same way, means being employed to effect the necessary adjust= ments of allsections simultaneously or at one operation.

In the example illustrated, the selection of blades of the main set is controlled by a main vertically adjustable bar which can be set in different vertical positions'to vary the number of blades operatively connected to the actuating slide, and the selection of blades of the ble rod which determines their vertical set position, but the supplemental bar or bars 18 or are mounted on thesupporting rod so that it or they can be adjusted relatively to the main bar, and it is by means of this relative adjustment that the supplemental set or sets of blades is or are connected to and disconnected from the actuating slide irrespective of the adjusted position of the main bar.

To be more specific, and for the sake of clearness confining the description here to the first embodiment, the two vertically adjustablebars (main and supplemental) are formed .in one of their side faces with thru-cuts or grooves which are adapted to be moved into or out of register according to the relative adjusted position of the two bars. '\When the grooves are in register, the two bars will clear and by way of example, and obviously many connectionbetween such blades and the ating slide.

the ejector blades of the'supplemental section and hence free that section from connection with the actuating slide; whereas, when the 'grooves are out of register, the supplemental bar'will, when the actuatingslide moves forward, pick up the blades of the supplemental section (according to its vertically adjusted position) and hence establish an operative 'In the accompanying drawings, the invention has been shown'merely 1n preferred form 1 changes and modifications may be made therein and in its mode of application without departing from the spirit of the invention.

It should be understood, therefore, that the invention is not limited to any specific form. .or embodiment except insofar as such limitations are speclfied in the appended claims.

As shown in Fig. 1", the mold wheel A is provided with one or more slug casting molds A which are adjustable both as to length and width of the mold slot or cavity. Ordinarily,fourmolds of different sizes are mount ed on the wheel, and the latter is manually adjusted to bring any selected mold into use. As before intimated, the selected mold may be one for casting a thin orthick slug. The thin slugs are usually of the plain or solid variety, Whereas the thicker slugs are usually of the ribbed or recessed variety as shown in Figsp2 and 3, where it will be seen that the ribbed slug therein illustrated comprises a solid'body-portion 1, an overhanging typecarrying portion 2,and a series of ribs 3 cast on the side of the body portion and giving support to the overhanging portion. The mold A for casting such a ribbed slug is of course shaped or fashioned to correspond,

'it being sufficient to say that the ribs 3 are cast in fore-and-aft grooves formed in the cap portion of the mold. If any further information is desired as to the form of construction of the mold and slugs, reference may be had to the Hall patent, No. 665,212.

The moldwheel A (see Fig. 3) is mounted for rotation upon the lateral arm A of a foreand-aft mold slide A 7, which latter is movedforwardly and backwardly in suitable guideways to carry the active mold into and out of contact with the composed matrix line, all in the usual way.-

Coming now to the present invention, and referring first to the embodiment illustrated in Figs. 1 to 7, the improved ejecting mechanism includes, as usual, a fore-and-aft actuating slide B mounted for reciprocation in the mold slide A and operated in the regular way thru a connecting link B from the main drive shaft of the machine. The ejector proper is made up of the main section C which may be used alone when casting thin' slugs, and a supplemental section D which may be used conjointly with. the main section when casting thicker slugs of the ribbed va'rietv. Both sections are freely adjustable in width to correspond to slugs of different lengths.

The main ejector section C is similar in all respects to the regularejector as used in the commercial linotype machine, or as illustrated in the Rogers patent before referred to. Thus, it comprises a series of vertically disposed blades C arranged edge to edge in contacting relation, a corresponding series of horizontally disposed slides 0 and a vertically adjustable bar C which controls the connection of the ejector blades to and from the actuating slide B. The ejector blades C and their slides C are both supported in the mold slide A in the usual manner, the slides being freely movable in fore-and-aft grooves formed in the side face of the mold slide, as shown. At their forward ends, the slides C are provided with rectangular lugs c which fit into corresponding holes or openings formed in the rear ends of'the ejector blades; and at their rear ends, the slides C are provided with similar rectangular lugs c for engagement with the forward edge of the vertically adjustable bar C The bar C also as usual) is mounted to slide vertically in a grooved guideway 0 formed in the actuating slide B, the opposite edges of the groove snuglv engaging the opposite edges of the bar so that the latter is caused to move forwardly and backwardly with the actuating slide. At its lower end, the bar C is slidablv sup ported upon a long fore-and-aft rod C carried by a vertically adjustable slide C nerated by a hand lever 0 extended to the front of the machine. 0

Bv means of the above arrangement (all of which is fully disclosed in the Rogerspa ent) the bar C may be set in different verticalpos itions to connect any desired number of blades C with the actuating slide B. Thus. as shown in Fig. 2. the bar C is seem connect eleven of the blades 0 (counting from the bottom) to the actuating slide B,

leaving the three uppermost blades'free or disconnected from the slide.- I Hence, when the slide B is moved forward to expel the cast slug from the mold, the bar C is moved with it, its forward edge engaging the lugs c on Referring now to thesupplemental ejector section D, it is an entirely new element added to the machine, comprising a series of blades D disposed horizontally in superposed parallel relation alongside the main blades C Since these blades D are designed only to engage the ribs 3 of the cast slugs, they do not need to be arranged in face to face contact,but are spaced apart to agree with the spacingof the slug ribs, which may be uniform or otherwise. Due to the wider spacing of the blades D their number is only half that of the main blades C there being one supplemental blade D for every other main blade C Being disposed 'fiatwise, the blades D do not require the use of separate actuating slides, such as the slides C for the main blades, and instead they are made long enough to extend from the forward ends of the main blades C to the adjustable bar C so as to be operated directly by the latter or the supplemental bar which it carries. At their forward ends the blades D are slidably supported in horizontal guides formed in a block or rack A attached to the mold slide A and at their rear ends, the blades are similarly 7 supported in horizontal guides d formed in the forward end of the actuating slide B. The tongues B left on the slide B by the formation of the guides d are cut awayat the side, as at B to clear the rack A when the slideis advanced for the ejection of the slug (see Fig. 3). r

The selection of the blades D is controlled a second or supplemental vertically adjustable bar D dove-ta led to the main bar C F ig. This supplemental bar D like the main bar C is slidable at its lower end upon the supporting rod C and hence willbe adjusted upwardly and downwardly with the bar C when the hand lever C is operated;

However the sup lemental bar D is intend- 7 V t o 7 ed to have an independent vertical movement relative to the main bar C and to this end,

the sun ortin rod C is )rovide-d with a rotary cam or eccentric D arranged in en gagement with an arm D extending laterally from'the lower end of the bar D (see particula rly Figs. 5, and 6). As will be evident, when the eccentric is turned in one direction.

it will shift the bar D to its upper position relatively to the bar C as in Fig. 5, whereas when the eccentric is turned in'the opposite direction, it will shift the bar D? to its lower position relatively to the bar 0 as in Fig. 6. To insure the lowering of the bar I) in the latter operation, there is employed a compres sion springD which is anchored atone end in the bar C and which presses downwardly at its free end on the arm D A -pair of handles D is employed for the turning of the eccentric, and a stop pin D mounted on the bar C serves in cooperationwith the handles to limit the rotation of the eccentric in opposite directions.

As shown in several of the figures, the main bar C isformed in its outer side face with a series of fore-and-aft'cuts or grooves 0*, one for each of the supplemental ejector blades D and the supplemental bar I) is formed in its outer sideface with a similar series of cuts or grooves 6%. In the diflerentladjusted positions of the bar (lithe grooves c are arranged to aline with the supplementalejector blades D so that the bar in moving lorward'with the actuating slide B will clear the supplemental blades and act only upon the slides C for the main blades C I The relative adjustment of the bar D is intended to permit or prevent such clearance between the bar C and the supplemental ejector blades D Thus, when the bar D occupies its lower position in relation to the bar 0 the grooves (Z stand in register with the grooves 0 and hence neither bar will engage the supplemental blades D when the actuating slide B is moved. forwardly (see Fig. 6). On the other hand, when the bar D occupies its upper position in relation to the bar C the grooves 0 will stand out of register with the grooves (Z and hence when the slide B is moved forwardly, the solid portions of the bar D (which now stand across the grooves 0 see Figs; 2 and 5), will engage the rear ends of the blades D and thus push the blades forwardly (see Fig. 4).

In this connection, it may be noted that the lugs 0 of the slides C are disposed forwardly of the solid edge of the bar G with which theyalways engage, for a distance about equal to that between the solid edge portion of the bar D and the rear ends of the blades D so I that as a result the twoejector sections will be operated in proper unison.

In providing for the return of the supplemental blades D after actuation by the slide B, the blades are termed intermediate of their length with clown-turned portions or lugs (1 (see Flgs. 2 and 7) which are located behind lu s 0 formed on the slides C for the main ejector blades C or at least those slides C associated with the supplemental blades D From the foregoing description, it Wlll be s een that the improved e'jecting mechanism comprises a composite ejector which,while permanently mounted n the mach1ne,can be altered at will both in thickness and in width. The variation in width of the two ejector sections'is effected simultaneously by the operation of the common hand lever C thru the medium of the bars C and l) which are movable upwar ly or downwardly in unison in selecting the number of blades desired. The use of the main section alone or of both sections conjointly is controlled simply by adjusting the supplemental bar D with the aid of the eccentric D which when set in one position enables both bars 0 and D to clear the supplemental blades D, but which when set-in the'other position causes the supplementallbar D to pick up the supplemental blades D at or about the time that the main bar C picks up themain blades C 7 The modification illustrated in Figs. 9 to 14 differs from the first embodiment only in the, respect that a second supplemental ejector section E has been added. The main section C and the supplemental section D are the same as before described, and the parts are indicated by the same letters of reference, so that no further explanation is required. As to the second supplemental section, it is here shown as comprising a series of blades E disposed horizontally in edge to edge contact with the blades D of the first supplemental section.

The blades E are supported in a manner similar to the blades 1) and are controlled in use by a third vertically adjustable bar E dove-tailed at its upper and lower ends to spacing blocks E attached to, the bar D (see Fig. 9). Like the bars C and D the bar E is slidable on the supporting rod C and is adjustable relatively to the bars C and 1) by a rotary cam or eccentric E having operating handles FF cooperating with a stop pin E which in this instance serves as a stop for the handles D of the eccentric D controlling the second bar D In this instance, too, the bars D. and E are nor mally urged downwardly and held in their' lower positions by tension springs E pulling downwardly on the bars from a fixed pin projecting from the bar C To complete the detail description, it is merely necessary to point out that the bar E is formed with transverse cuts or grooves 0* which may be shifted into and outof register with the blades E It is intended that the supplemental blades E .be used 1 only when the supplemental blades D are in use, and to bring that about,

the eccentrics Dtand. E are mutually formed to insure their proper cooperation. As best shown in Figs. 12, 13, and 14, the hub of the eccentric E for the third bar E is mounted to rotate about theextended hub-portion of the eccentric D for the second bar D The eccentric hub E is formed with a lug E arranged to engage a lug D on the eccentric hub D4; When both bars D? and E are in their lower positions, as shown in Figs. 8 and 9 with their eccentrics both facing downwardly, the lugs are in engagement as indicated in Fig. 12. Now if it were desired to use the supplemental blades D conjointly with the main blades but without the supplemental blades E the eccentric D is rotated to elevate the bar D alone, the lug D breaking contact with the lug Emmi 1Q, leaving. theeccentric E* undisturbed (see Fig. 13). 'If later it should be desired to bring into use the second supplemental set of blades B, then the eccentric E is rotated to elevate the bar E leaving the eccentric D? undisturbed and bringing the lug E again into contactwith the lug D (see Fig;

14);" By operating the eccentrics E* and D in reverse manner, the supplemental blades E may first be disconnected from the actii ating slide B and then the supplemental blades D If both sets of supplemental bladesare to be disconnected from the actuating slide, this can be accomplished atone operation byturning the eccentric D back to its original position, as under suchcircumstances the lug D will engage the lug E the latter has not already been operated for 9 the raising of the barD so that in no case will it result that the second supplemental set of ejector blades can be used without the first supplemental set.

Since both supplemental sets of ejector 5 blades are used together, the return of the blades E may be readily eifected by the simple expedient shown in Fig. 10, whereit will be seen that the blades E are formed at their rear ends with laterally extending 0 lugs c engaged in notches'e formed in the corner edges ,of the blades D The blades D are thus free to move forwardly without the blades E but will act to return the latter blades when the two sets are used conjointly.
